CarPlay Disconnecting - iPhone XS Max

So can we 'confirm' that WiFi is not the issue? You have WiFi on but fully deleted Google Maps, right? I will try the same.

Wonder if Google can update the app so it doesn't conflict - perhaps it is an issue with the virtual cockpit having Google maps as well?

That is how I see it but I’m not a software engineer. It has been the only solution for me that has produced a result that I can live with. Not happy about “losing” Google Maps but I use Waze on the commute. Still frustrated by this entire experience.

Have a call this PM with Apple support. Hopefully that will go well. They found another problem with the iOS that they needed to work on. Apparently how they collect data from our phones during issues like this is not working correctly as well. So they cannot “see” what is happening.

Definitely far from resolved. Driving in to work this morning my phone stayed connected for one hour while i listened to Apple Music and had Waze loaded (This morning Google Maps was still installed on my phone). This afternoon, after reading the posts on this thread, I uninstalled Google Maps before leaving work. Got in the car, launched CarPlay with Waze, and received a phone call over Google Voice. 5 minutes into my call, phone disconnected from CarPlay. Each time I tried to reconnect, it would last 1 -2 minutes max before disconnecting again. It disconnected regardless of what CarPlay apps I was running. I reconnected and disconnected 6 or 7 times before I got fed up and stopped. In 50 - 75 percent of the cases that the disconnects have occurred since I’ve had the IPhone XS Max, it’s been within a few minutes of making or receiving phone calls while in CarPlay. Not sure if this is coincidence or if the phone calls destablize the OS. Frustrating.

Same here. So after reading this thread, I uninstalled google maps to see if that was the issue. Worked fine on my commute to work, but 3 disconnects on the way home. Turned off WiFi and haven’t had another disconnect yet. Going to try without WiFi on tomorrow and see how that goes. This is beyond frustrating. Should we start a new thread since this one said “solved” previously when this is still a legitimate ongoing issue???

Both. First I tried it as a restore from my iPhone X running 12.0. Then I wiped the thing and set it up as a new phone. Neither worked (nor did the replacement unit I got from the store). Just downloaded public beta 4. Will try again and report back.

Please my 3 months old iphone x didn't not on after getting hot and I switched it off immediately on the 9th of October 2018 uptill now I'm still unable to use my iphone x. Please kindly help me with customers care.

Dear all.

I'm writing from Chile, South America.

Have the same problem with a new Iphone XS connected to my 2018 Audi A5 Sportback. iOS 12.0.1

Carplay randomly disconnects. Sometimes every 10 minutes, sometimes every 10 seconds, etc, etc….

Tried all the possible solutions suggested in this community, but nothing work at the moment.

Today a tried turning off WIFI and Bluetooth in my iphone before connecting it to the car (USB 1) and finally I got a 30 minutes trip with no disconnections (Carplay Waze and Spotify working ok) .

I will try to continue testing this way during next days. Hope this works….

I have the same issue.

Audi S5 Sportsback 2018

I had an iPhone X and everything went perfect.

Now with the XS max nothing but disconnects.

I contacted apple support and then escalated it. They believe it is an issue with Audi not supporting the phone yet.

I was told I need to contact Audi and let them know.

Also having this very frustrating issue. I have a 2018 Audi Q5 and the Xs Max. Upgraded from the iPhone 7 and never had this annoying constant disconnect issue. There doesn’t seem to be a pattern for what triggers the random disconnecting for me. Please fix!

I checked with Audi and they pointed the finger at Apple. I find it hard to believe it’s on Audi’s end when previous phones and iOS 11 worked well. I seem to notice if I turn WiFi off it works better and then will disconnect as soon as WiFi turns back on or sometimes the phone automatically turns it back on too and it will disconnect. HIGHLY frustrating, would be great if Audi and apple could talk so this is fixed and we get the value out of these expensive items...

Exactly the same problem here. I’m in the UK with a 2017 S4 Avant. I noticed the the phone keeps going off and on charge, like the cable is being disconnected and reconnected. I also noticed a message in the MMI stating that the USB device has a power supply problem. Could the XS Max be drawing a little too much power from the car? All is fine when I connect it to a lighter socket charger.

I’ve been observing this problem and for me, the issue disappears when the iPhone XS MAX reaches 100% charge. This may be a coincidence but once it reached 100% I couldn’t replicate the issue...so it could be a power management issue? Could someone else see if this is the case for them?

You may be on to something...my phone was at 100% this morning, WiFi turned on and no disconnects. I can say with a good amount of confidence, it disconnects when it’s not at 100%...perhaps it is a power management issue with all the new stuff they added in. Can someone at Apple please read this and check to see if that will fix our problem?!?!?!
